The "Autism Spectrum Disorders-Diagnosis for Adults" ("ASD-DA") is a standardized assessment used to measure autistic symptomatology in adults with intellectual disabilities (ID). In order to further establish the validity of this measure, convergent validity of the "ASD-DA" was established by comparing "ASD-DA" total and subscales scores with the Pervasive Developmental Disorder/Autism (PDD/Autism) subscale score on the "Diagnostic Assessment for the Severely Handicapped-II" ("DASH-II"). Data was collected from 278 adults residing in two large supports and services centers in the southeastern region of the United States. The "ASD-DA" total scores and all subscale scores correlated with the PDD/Autism subscale score at the p less than 0.001 level, further supporting the validity of the "ASD-DA" as a valid measure of autistic symptoms in adults with ID. The implications of these findings are discussed. (Contains 2 tables.)
